The Fascinating Science Of Biomechanics: Understanding Human Movement
Ever stopped to consider what biomechanics is, and how that will permit you to comfortably stride across the room? Every step, from heel strike to push-off, is a subtle play of muscles, bones, and physics. This dance of the human body in motion follows a fascinating science: biomechanics. Role Of Biomechanics Biomechanics explores and reveals the how and why of human movement. It unlocks the secrets behind every jump, every throw, even the way we sit or stand. Understanding biomechanics principles develops a deep appreciation for the body’s remarkable design to both pull off delicate balance and explosive force. What is perhaps most important, though, is that biomechanics has little to do with athletic-performance skills. For example, the way we lift groceries to the many hours spent hunched over a computer, our posture and movement patterns can significantly affect our biological systems and overall health. Core Principles of Biomechanics Biomechanics is based on basic principles that rule how our bodies move. These concepts form the building blocks for understanding even the most complex athletic maneuvers. Let’s look at a few key ideas: Forces and Torques Consider the push-off of a jump. This motion is a result of the force your leg muscles generate. The science of biomechanics involves both internal forces-(which are generated by your muscles) and external forces-things like gravity and ground reaction force-that act on your body. It is pretty important to understand how these forces interact to ensure you move efficiently. Finally, torques-or twisting forces-are essential in rotating body segments to throw a ball or twist your torso effectively. Newton’s Laws of Motion You probably don’t remember that class on Sir Isaac Newton. In fact, his laws of motion might work about as well on the field as they do in the classroom. Newton’s First Law (Law of Inertia) tells you why it’s tough to get a body in motion to stop or a body at rest to begin to move, and his Second Law (Law of Acceleration) describes just how force affects the acceleration of an object, including our bodies. Biomechanics relates these principles to understand how forces acting on us can cause us to begin to move, stop moving, or change direction. Center Of Gravity (CoG) Imagine your body to be a kind of inverted pendulum. The CoG is that pivot or point of suspension at which all of the weight of the body appears to be located. Any movement away from an optimal balance of the CoG therefore can compromise stability. Biomechanics helps us understand how posture and movement patterns affect our CoG, and so influence our balance and fall risk. Kinesiology This is quite in contrast with biomechanics, which may be used strictly in the mechanics of movement. On the other hand, kinesiology broadly encompasses the study of human movements coupled with aspects including anatomy, physiology, and psychology. Understanding these concepts-be it biomechanics or kinesiology-provides one with a broad appreciation of how our body moves and functions. Biomechanics is a very crucial field that enhances athletic performance and assists us in our health and fitness activities. The exploration of its principles reveals what is intuitive, namely, the complexity and efficiency of human movement. The Sportz Planet Desk,Atharva Shetye
Kinetic Chains in Athletic Functionality
Kinetic chain is also another term that is used to refer to the performance of the musculoskeletal system in sports. Instead of individual muscles acting independently, it is usually a system of working bodies, termed as kinetic chain. It refers to multiple joints and associated muscles acting together in order to power movements such as throwing, sprinting, or jumping. Sprinting: Power from the Bottom Up In the sprinting biomechanical study from the International Journal of Sports Science (2024), investigators calculated that 45% of sprinting speed is due to the proper activation of the kinetic chain from the ground up-the hips, knees, and ankles. So, proper timing of muscle activations from the bottom up is critical for maximum speed. Throwing Sports: Energy Transfer in Action Overhead and horizontal throwing sports, such as cricket and baseball, make extensive use of upper body kinetic chains. According to a 2024 report in the Journal of Sports Biomechanics, more than 60% of the forces that provide throwing velocity are obtained from the kinetic transfer initiated from the legs, followed through by the torso and concluded by the arm and wrist. Jumping: Optimizing Vertical Power According to Sports Biomechanics Reviews, research reveals that athletic activity like basketball and volleyball could be accomplished with a proper kinetic chain between the legs and the core in a jump. With synchronization between the legs and the core, it is possible to increase a difference of 12 to 15% in vertical jump height. In case there is no synchronization, then there is the probability of losing some energy in the athlete, which eventually leads to poor performance in activities. Injury Prevention Through Kinetic Chains One of the major reasons for injury prevention is an understanding of training the kinetic chain. Poor coordination between these muscle groups leads to overuse injuries; according to the Sports Injury Epidemiology Journal, knee and ankle injuries will represent 40% of sports injuries by 2024.

Sports Biomechanics and Its Contribution Towards Athlete Development
The inaugural season of The Sportz Planet – SportSci Summit 2024 showcased a series of engaging panel discussions, addressing key topics such as Sports Physiology, Sports Psychology, Nutrition in weight category sports, CPR, Sports Wearables, and much more. Among these, the first panel discussion on Sports Biomechanics was moderated by Dr. Kenjom Ngomdir featured Ms. Priyanka Anie Kosle who was one of the panelists. Ms. Kosle offered profound insights into the critical role of biomechanics in athlete development. Understanding Sports Biomechanics Sports Biomechanics is the study of movement in sports, encompassing the analysis of body mechanics, muscle functions, and the impact of forces on the human body during physical activities. As Ms. Priyanka Anie Kosle highlighted during the discussion, biomechanics focuses on ensuring correct movements on the field to prevent injuries and enhance performance. “Biomechanics is the movement. Wrong movements on the field can hamper different groups of muscles. This can increase the chances of injuries, especially during crucial moments, like during a game day,” said Ms. Kosle. Importance at the Grassroot Level The importance of biomechanics becomes evident at the grassroots level, where young athletes are still learning and refining their movements. Ms. Kosle emphasized the need for precise monitoring of how students and athletes perform their exercises, drills, and training sessions. “There should be a check on how they are performing their exercises, drills, and training sessions. The coaches and the seniors have to make sure that the young athletes don’t practice the wrong way. For example, wrong movement of feet while running or even walking,” she added. Recent Statistics in Sports Biomechanics Recent studies and statistics further underscore the significance of biomechanics in sports: 1. Injury Prevention According to the American Orthopaedic Society for Sports Medicine, 70% of ACL injuries in athletes are due to improper biomechanics during movements like jumping and landing. Proper biomechanical training can reduce this risk significantly. 2. Performance Enhancement A study published in the Journal of Sports Sciences found that athletes who underwent biomechanical analysis and training improved their performance by an average of 15% over six months. This improvement was seen in various metrics, including speed, agility, and strength. 3. Youth Athletes Research from the International Journal of Sports Physical Therapy indicates that early intervention and biomechanical education in youth athletes can reduce the likelihood of chronic injuries by 50%. This highlights the importance of implementing biomechanics training at a young age. 4. Technological Advancements The use of wearables and motion capture technology in biomechanics has surged by 40% in the last five years, as reported by Sports Tech Research. These advancements enable real-time analysis and feedback, allowing for immediate corrections and enhanced training protocols. From injury prevention to performance enhancement, biomechanics offers invaluable benefits that can shape the future of sports. As the field continues to evolve with technological advancements, it promises to provide even more precise and effective training methods for athletes at all levels.
